The Miller Smith 320 Series High Purity Two-Stage Regulator is engineered for the most demanding specialty gas applications. Designed specifically for use with corrosive and non-corrosive gases, this regulator features a robust 316 Stainless Steel bar stock body and wetted parts, ensuring exceptional resistance to corrosion and maintaining the integrity of high-purity gas streams. The inclusion of a 316 Stainless Steel filtered seat further enhances purity while extending the service life of the unit by preventing particulate contamination.
Precision control is achieved through a convoluted stainless steel diaphragm that offers superior sensitivity to pressure changes. Unlike standard elastomeric diaphragms, the metal-to-metal diaphragm seal provides maximum leak integrity, a critical requirement when handling hazardous or expensive specialty gases. As a two-stage regulator, it delivers a constant outlet pressure of 0-25 PSI regardless of fluctuations in the cylinder pressure, making it ideal for analytical instruments and process control where stability is paramount.
Safety and versatility are core to the 320 Series design. The regulator is equipped with captured vent ports (1/16" FNPT) in the bonnet, allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. It is also designed to withstand internal vacuums, facilitating effective purging operations during cylinder changes. With a CGA 320 inlet connection, this model is specifically configured for Carbon Dioxide (CO2) service, providing a reliable solution for laboratories and industrial facilities requiring high-purity CO2 delivery.
